Please note that I tried to break this question up into three relevant sections, separated by the large headers
Here's what happened to the cabinet
I was moving an empty wood file cabinet down some stairs; I goofed, which caused the back casters to get ripped out of the bottom of the wood part of the cabinet. As a result, on the bottom face, and part of the back edge on the cabinet were damaged. I'll need some wood filler.
Here's how the cabinet & casters look.
Here's my plan
The Resources I have
I'm able to clamp a board along the edge to keep it straight. I also have all kinds of glue, I was able to recover some parts of the MDF that came loose (I have sawdust, I have access to scrap paper (for paper pulp), I have similar veneer, I have similar stain, and I have a few other relevant tools for the job.
Fixing the MDF: I'm planning on mixing a glue/sawdust/wood-filler/mdf/sawdust mixture up, clamping the board in place, applying the glue, letting the glue dry, removing the clamps and board, and then sanding it down.
Fixing the edge: If it looks good; I won't veneer it over. However, if it's bad, I'll sand it all down, and then apply new veneer. After the veneer's applied, I'll finish it.
Reapplying the casters: For this step, I'll just put them further towards the front slightly, maybe an inch or two depending on what I need. This will be done to ensure the casters are secured.
Clarification on the question & Answers I'd like
Clarification My main question is with regards in the wood filler used. The bottom panel of the cabinet is maybe 3/4" thick, and of that 3/4" maybe 1/8" or 1/16" is affected by the missing mdf. I want it to be smooth when I remove the clamped board, so that minimal wood filler sticks to it. I.E., when I remove the board I don't want to take any MDF with it.
Answers I'd like
Is there a specific kind of filler that would set well? If so, how much sawdust do I use?
Thank you friends!
